No Sound Output
If you experience no sound from your Onn CD player, initially verify the volume level is appropriately adjusted. Ensure the correct source (CD, Radio, Bluetooth, Aux-In) is selected using the Source Switch. Check that headphones are not plugged into the headphone jack, as this may disable the speakers.
Test with a different audio source, like a different CD or a Bluetooth device, to isolate the problem. If using auxiliary input, confirm the external device’s volume is up.
Refer to the manual for detailed troubleshooting steps and safety precautions regarding audio output.
Remote Control Issues (if applicable)
